Williams, the five-time Pro Bowler who's spent his entire career with the Bills, turns 35 this summer but has missed just 12 combined games since 2012 and 23 over his entire career.

Williams is reportedly receiving $6 million with $5 million guaranteed. "I'm grateful for the guys in this locker room and the year that we had and the opportunity to work with them and play with them".

Williams showed no signs of slowing down last season making 16 starts while contributing 41 tackles and finishing second on the team in sacks.

The Bills' depth at defensive tackle, among other positions, appeared to be severly lacking.

"You know how I feel about Kyle and what he's meant to our community in Buffalo over the years and what he's meant to our football team", said McDermott. "He meant a lot to me this past season in connecting my message to the locker room at different points throughout the year". It's got to be right, obviously for Kyle and his family, and our situation as well.

After losing Eric Wood to an early retirement this offseason, the Bills could use Williams' leadership in the locker room.
